Button



Patented Nov. 17, 1936 UNITED STATES PATENT GFFICE BUTTON Application January 15, 1935, Serial No. 1,925

2 Claims.

My invention aims to provide improvements in buttons and like devices, especially that type employing an attaching member in connection with a main button member.

In the drawing, which illustrates a preferred form of my inventionz Figure 1 is a side view of a complete button embodying my invention;

Fig. 2 is an enlarged section taken on the line 2 2 of Fig. 1;

Fig. 3 is an enlarged section taken on the line 3-3 of Fig. 2;

Fig. 4 is an enlarged section through the component parts of a button before assembly;

Fig. 5 is a side View of the attaching member per se before assembly with a button;

Fig. 6 is another side View of the attaching member per se showing the formation of the eye; and

Fig. 7 is an end view of the attaching member per se, the dotted portions indicating the interior construction.

The specific form of my invention which I have chosen for purposes of description comprises a button part I and an attaching member 2 (Fig. 1) secured to the rear face of the button.

Referring first to the attaching member 2, as illustrated in Figs. 5-7, I have shown a device formed from a single piece of sheet metal drawn to a substantially tubular form and having an outwardly flaring flange 3 at its open end. A special feature of this flange is the bevelled edge lt, the purpose of which will be explained in connection with a description of the complete button. The opposite end of the member 2 is closed and rounded to present smooth surfaces on all sides. An aperture 5 is formed in the member for attaching the completed button to a garment and the like supporting member. The walls 6 of the aperture are rolled in to provide smooth bearing surfaces for the thread or other attaching material, thereby preventing any cutting or fraying of the thread (Fig. 6)

The button member I may be in any desired shape, and from any desired material; preferably one which may be machined or molded, and which will be substantially hard and rigid when complete. A circular depression l is formed in the rear face of the button, so that the bottom of the depression is of greater diameter than the opening. Thus the walls 0 of the depression form a continuous shoulder facing away from the outer surface of the button. This depression is preferably slightly deeper than the thickness of the metal in the flange of the attaching member; and the diameter of the depression is somewhat greater than the outside diameter of the flange of the attaching member. To assemble the attaching member with the button, the flange 3 is placed in the depression l and with a suitable tool the flange is flattened down until it takes the position shown in Figs. 2 and 3. During this flattening operation, the bevelled edge 4 of the flange rolls outwardly unt-il it abuts the slanting walls 8 of the depression. This makes a very secure assembly since the flange cannot come loose from the walls 8 unless it is forcibly bent back to its original shape.

It should be understood that this manner of securing an attaching member, and the attaching member itself, are applicable to devices other than buttons and therefore, while I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby as the scope of my invention is best defined by the following claims.

I claim:

1. A button and the like device comprising, in combination, a body portion of relatively inextensible material having a depression at one face thereof, the walls surrounding said depression providing shoulders facing the base of said depression, and a one-piece attaching member of the class described, said member comprising only a tubular body portion having one closed end, said member having a pair of apertures through opposite points in the wall thereof adjacent to said closed end, the walls of said apertures being rolled inwardly toward each other to form an aperture having substantially continuous walls for the purpose described, and a bell-shaped flange integral with and extending outwardly from the opposite end of said member, said flange located entirely within said depression and having inwardly-sloping free edges bearing outwardly against the Walls of said depression behind said shoulders thereby providing the sole means whereby the two parts are maintained in permanent assembly.

2. A one-piece attaching member of the class described, said member comprising only a substantially tubular body portion having one closed end, said member having a pair of apertures through opposite points in the walls thereof adjacent to said closed end, the Walls of said apertures being rolled inwardly toward each other to form an aperture having substantially continuous walls for the purpose described, and a bell-shaped flange integral with and extending outwardly from the opposite end of said member and adapted to be flattened and expanded for engagement with an apertured device, said flange having inwardly-sloping free edges.
